NTE1775
Integrated Circuit
PIF Subsytem for TV Receiver
Description:
The NTE1775 is a picture IF subsystem that provides 3–stage IF amplifier, Video Detector, black and
white noise inverting circuits and AFT detector for a TV receiver.
The NTE1775 also provides internal fast response AGC with dual time constants for the IF amplifier
stages and delayed AGC for an external RF amplifier stage. It is designed for FET top front–end
(reverse AGC).
